Building an army in a short space of time is a very difficult task. To be sure, there are some impressive examples. Cromwell’s republican New Model Army was put together while the English Civil War was already underway; Washington’s army of U.S. Independence quickly wore down and beat the British in the 18th century; Napoleon’s revolutionary army was born from the French Revolution and swept all Europe before it; the Red Army of the Soviet Union was forged from the chaos of its defeat in World War I.
But the list of failures is just as spectacular. The South Vietnamese Army boasted billions of dollars, up-to-date equipment and state-of-the-art training, but couldn’t control even South Vietnam itself. It ultimately surprised observers only by holding on as long as it did after the Americans left.
The Soviet Union similarly built up the communist army in Afghanistan but always distrusted it as a fighting force; it ultimately suffered mass desertions.
